HDTUNE PRO 4.61
One thing that became very apparent when using the Patriots was the excellent latency that we were receiving. A PCIe raid card allows the SSD to function at its very best, eliminating much of the overhead and latency of some other connection methods. The LSI 9265-8i is a great performer and allowed for some of the best latencies that we have seen with SSDs. In this first test, you will note that the latency is .061 ms for the 4k random access whereas, in previous testing with a array of 8 C300 SSDs, the result was .108 ms which is nearly twice the latency you will see here. The extreme low latency is very important as it illustrates the ‘snappiness’ of the solution overall.
In this test of latency we note that the measurement of 4k Random is slightly better at .056 ms. With a comparable array of C300, we received .107 ms. The results from the Wildfires are almost double the C300 array across the board.
To verify the latency was actually this low, we did a quick run with AIDA 64, a great program for latency measurements. One of the benefits of using AIDA 64 is that you can see the visual representation of the latency over a period of time. This can help to show that the latency received is constant and sustainable. Here the latency is being measured with 64 KB which is the AIDA standard for latency measurement. The results for the array of 8 C300 was .10 ms, quite a bit higher than this excellent .04ms that we received here. This is the lowest AIDA latency measurement that I have ever seen with any raid card or SSD!
